Automotive Castings Plant Baghouse System

Baghouse Project Summary
 

An industry leader in automotive castings required an extensive three part air pollution control system to capture a significant amount of silica, sand, and metallic dust and fumes created at several processing points in the work environment.

USAF manufactured and installed four turnkey baghouse systems from the ground up including a dual baghouse system outside the plant and two internal units. Complete installation included all concrete, electrical, duct work, equipment, and baghouse install. Airflow for the entire system captures nearly 200,000 CFM dust and fumes with an average 4 to 1 air-to-cloth filter ratio across all units.

The dual outdoor pulse-jet baghouse system provides ventilation and capture of dust and fumes generated during mold pouring, mold cooling, shake-out, casting sorting and blast cabinet processing. Another baghouse was installed in the plant to provide ventilation and capture of silica and sand dust created at sand cooler, sand bins, bucket elevators, aerator, mullor, sand transfer points. The fourth baghouse unit was installed to ventilate the close captured furnace charging & melting process.

Features of the project include enclosed hoppers for the outside units, emission testing platforms installed on all units, PTFE treated filter bags, bag leak detectors and an advanced state of the art electrical system for on all three baghouse system which included Variable Frequency Drives (VFD), Programmable Logic Controllers (PLC) and HMI touch screens , system protection field devices, and exterior & interior lighting.
